Configuring Traversal Server Zones
A VCS Expressway can act as a traversal server, providing firewall traversal on behalf of traversal clients (a VCS

For firewall traversal to work, the traversal server (VCS Expressway) must have a special type of two-way relationship
with each traversal client. To create this connection between a VCS Expressway and a VCS Control, see

Note:
to make sure that traversal zones to work.
After you have neighbored with the traversal client you can:
■
provide firewall traversal services to the traversal client
■
query the traversal client about its endpoints
■
apply transforms to any queries before they are sent to the traversal client
■
control the bandwidth used for calls between your local VCS and the traversal client
■
view zone status information, including the connection addresses
Note:
Connection addresses listed in the status information may have been translated by a NAT element
between the traversal server zone and the originating device.
